Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
Symptoms:
- High stall speed
- Excess TCC slip RPM & related codes
- Delayed engagement
- Poor fuel economy
Cause:
The converter charge control valve is a separation between converter oil and lube oil pressure. The converter limit valve controls the separation of converter oil and cooler oil. As either bore becomes worn, leakage causes the converter pressure to drop.Correction:
Ream the converter limit or converter charge control valve bore and install the oversized valve kit to correct the TC circuit pressure.TAAT

Saturn TAAT units may suffer from delayed engagements and loss of lockup. These conditions can be caused by bore wear in the converter limit valve and the converter charge control valve. Wear in either valve bore causes loss of TC pressure, which can also cause a high stall condition and even poor fuel economy. Sonnax offers the oversized converter limit or converter charge control valve kit 95200-08K to restore the valve bores and fix the low converter pressure problems.
- 瓦尔ve has annular grooves for better centering in the bore
- 瓦尔ve is hardcoat anodized to reduce wear
- 瓦尔ve utilizes metering notches for smooth valve function
Fits both MP-6 and MP-7 units, 1991-2002. Kit contains one valve which can be used in either bore with the proper selective spring.
